DRUM.

Specification of Letters Patent.

Patented Jan. 28, 1 908.

Application filed April 23 1907' Serial No. 369.847.

To all whom it may concern:

Be it known that I, ATHERTON D. CON- vnnsn, a citizen of the UnitedStates, and a resident of Vinchcndon, in the county of Vorcester andState of Massachusetts, have invented a new and useful Improvement inDrums, of which the following is a full, clear, and exact description.

The purpose of the invention is to provide a means for effectivelymaintaining the rim of a drum upon the flesh or tuck hoop, no matterwhat character of head is employed, or whether the cords at one point betightened more than at other points, and means serving under allconditions of use to prevent the rim from shifting from its trueposition rela tively to the head.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth' applied; and Fig.2 is a vertical section through a part of the head portion of a drumillustrating a slightly different adaptation of the stay.

My invention relates particularly to means for maintaining the rims of adrum in normal position relatively to the heads and the flesh or tuckhoops when the heads are made of fiber or from material other thansheep-skin, but the application may be also made when sheepskin headsare employed, if desired, but since a fiber head cannot be stretched asmuch or as safely as a head of sheep-skin, hence the necessity ofinsuring the rims always remaining in position, they being prone todisplacement under ordinary conditions when used especially inconnection with said fiber heads.

A represents the body of a drum, which is provided at the top and at thebottom with the customary interiorly located strengthen- Each endportion of the body is provided with the customary flesh or tuck hoop 10and head 1 1, which heads are wrapped at the edges around the flesh ortuck hoops which heads after being passed around the flesh or tuck hoopsextend to the interior of the body A, as is shown in the drawings.

In connection with each flesh or tuck hoop a rim 13 is employed, andthese rims are adapted to rest upon the outer faces of the flesh or tuckhoops 10. In connection with each rim and its accompanying flesh or tuckhoop two or more stays B are employed. These stays may be and preferablyare made of sheet metal and the metal may be a spring metal, but it isnot absolutely necessary. Preferably these stays consist of a singlestrip 14 of material adapted to extend along the outer face of a rim 13and over and in engagement with the tuck or flesh hoop upon which therim rests, as is shown in Fig. 1. Also these stays B may be secured tothe rims 13 in any suitable or approved manner; they are preferablyattached to the rims by means of eyelets 15 so that the said eyelets notonly serve as fastening devices for the stays, but likewise act toreceive the tightening cords 16 for the drum, as is shown in Fig. 1.

In Fig. 2 I have illustrated a slight departure in the formation of thestays. The stays in Fig. 2 are designated as B, and each of the saidstays consists of a lower section 17 that is riveted or otherwisesecured to the outer face of the body A of the drum, and an upperangular portion 18 whose upper member engages with the outer face of aflesh or tuck hoop 10 and accompanying rim 13.

It will be observed that when either form of stay is employed, the rimsare eflectually prevented from shifting from their set position over orto a bearing against the flesh or tuck hoops, so that under nopossibility can a rim be shifted so as to uncover a portion of itsaccompanying tuck hoop, and thus the liability of the head beingloosened is very remote even under the most severe conditions of usage.

Having thus described my invention, I claim as new and desire to secureby Letters Patent,

1. In a drum, the combination with the body, the flesh or tuck hoopsurrounding the body at the end, the head carried by the tuck hoop andresting on the edge of the body, and the rim, of a plurality of fixedstays spaced apart and engaging with the flesh or tuck hoop and the rim,the said stays preventing the mm from shifting, and mainplainc'ing it inposition relatively to the said ea 2. In a drum, the combination withthe body, the flesh or tuck hoops encircling the body at the ends, theheads carried by the tuck hoops and the rims in alinement with the tuckhoops, of a plurality of stays located at each end of the drum and eachcomprising a metal strip engaging the outer faces of the tuck hoops andthe rims, the said stays being rigidly secured to a part of the drum.

3. In a drum, the combination with the body, a flesh or tuck hoop, ahead and a rim, of metal stays for preventing the rim from shiftingrelatively to the head and the flesh or tuck hoop, the said stays beingin engagement with the outer faces of said rim and tuck hoop, andfastening devices extending through the stays and rigidly securing themto a part of the drum.

4. In a drum, the combination with a body, the tuck hoops engaging theouter face of the body at each end thereof, the heads carried therebyand the rims, of stays rigidly secured to the rims at their outer facesand extending to an engagement with the outer faces of the tuck hoops.

5. In a drum, the combination with the body, the tuck hoops, the headscarried by the said hoops, and the rims, of stays located at the outsideof the rims and extending to an engagement with the outside faces of thetuck hoops, and eyelets securing the said stays to the said rims,through which eyelets the tightening ropes may be passed.

6. In a drum, the combination with the body, the tuck hoops encirclingthe body at the ends, the heads carried by said tuck hoops, and the rimsadapted to rest upon the tuck hoops, of stays comprising metal stripsrigidly secured to the outer faces of the rims and extending intoengagement with the outer faces of the tuck hoops.

In testimony whereof I have signed my name to this specification in thepresence of twosubscribing witnesses.
